Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed April 1,1985. Serial No. 253,221

' To (all whorrt it new concern:

' county of Rensselaer, and State of New York,

have invented certain new and useful Improvements in Brush- Filling Machines, of which the following is a specification.

The invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described and subse uently claimed.

Reference may he had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several i ures therein.

Figure 1 oi the drawings is a vertical crosssection of my improved brush-filling machine. Fig. 2 is a vertical longitudinal section of the same, taken on the broken line 2 2 in Fig. 1. Fig. 3 is a horizontal cross-section taken on the broken line 3 3 in Fig. 1

My invention relates to improvements in the class of machines an example of which is shown and described in United States Letters Patent No. 57 0,604, granted November 3, 1896, to William Morrison for improvements in brush-machines, to which patent reference may be had for a more complete understanding of the present invention.

The object of the invention is to facilitate the insertion or seating of the bristles in the apertures in the bristle-receiving plateavhich plate may be a perforated brush-hack or a separate plate adapted to afford temporary support only for the tufts of bristles during the operation of making the brush.

Referring to the drawings, wherein one form of the invention is illustrated, 1 is a table supported upon uprights 2 and having a box 3 open at the front of the machine toward the o crater, as at 4.

Mounte upon the outer sides of the end walls of the box are slideways 5, adapted to receive slidelates 6, reciprocatory vertically therein, whie slide-plates are connected, respectively, by a pitman 7 with a crank-pin 8 on the crank-shaft 9, adapted to be driven by means of a belt applied to the pulley 10 thereon.

A meshed or reticulated bristle-agitator 11 extends from end to end'of the box or chamher 3 and is connected at each end by an arm 12 with the upper end of the neighboring slide-plate 6, whereby said agitator is more or less violently agitated by means of said crankshaft and interposed mechanism. The arms 12 project through apertures in the ends of the walls of the box adapted to permit the necessar movement. The bristle-agitator 1'1, whic is shown in the drawings herein in the form of a continuous substantially flat bed, may be of any known form, provided only that it be adapted to form a reticulated. meshed, or epen-work support for the bristles which are placed thereupon promiscuously, and when vilirated or agitated the bristles are caused to assume various positions, in some of which positions the ends of the bristles enter the openings and are guided therethrough in approximately vertical lines.

Beneath the agitator 11 is a plate-support or table 13, adapted to receive one or more bristle-receiving plates 14, which may be the bristle-receiving plates shown and described particularly in said patent or any other kind of bristlereceiving plate adapted to support in groups or tufts bristles inserted in apertures therein.

While it is necessary that this bed which supports the bristle-receiving plates should be substantially stationary in its relationship to the ar itator 11 that is, that it should not partalie of'the violent reciprocating motion of the agitatorl have ascertained that it is desirable to impart to said substantially stationary bed a slight jarring vertical movement from time to time not necessarily corresponding with the movement of the agitator as to either time or amplitude, which vertical jarring movements serve to cause the bristles to settle and pack together more firmly in tufts in the apertures in the bristlereceiving plate. The jarring movement of the bed 13 referred to may be accomplished in any known manner.

I have shown the bed 13 mounted upon the upper ends of a pair of rods 15, the lower ends of which are connected with a vibratory frame 16, hin ed at 17 to the frame of the machine, whic frame 16 rests upon a camdisk 18, fixed upon the shaft 19. The shaft 19 is driven from the main drive-shaft 20 by means of a belt 21 and pulleys 22 and 23 on the respective shafts 19 and 20. The crankshaft 9 is also driven from the main driveshaft 20 by means of the belt 2-4 and the pulleys if) and 25, fixed upon the respective shafts 9 and 20. The cam-disk 18 is provided with a cam 26, adapted at each rotation of the cam-disk to raise slightly the vibratory frame 16, and when said cam asses out of engagement with the frame 16 t e latter is permitted to drop back a ainst the smaller portion of the cam-disk wit a jarring motion which accomplishes the object sought.

I have shown the pulleys 22 and 25 as comparatively large and the pulleys 23 and 10 as comparatively small, whereby the shaft 9 is caused to rotate at much greater speed than the shaft 19, and the cam 26 and crank 8 are so proportioned that the amplitude of movement of the agitator is much greater than that of the bed 18; but the fre uency and am litude of the movements of t e agitator an the bed 13 may be varied as desired to meet different conditions in use.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a machine of the class described, the combination with a bristle-feeding bristleagitator; of a support for a bristle-receiving plate below the agitator; and means for imparting to said su port jarring movements independently of t 1e movements of said agitator.

2. In a machine of the class described, the combination with a bristle-feeding bristleagitator; and mechanism for a itatin the same; of a support for a brist e-receiving plate below the agitator; and means for imparting to 'said support jarring vertical movements of less amplltude than the movements of said agitator.

3. In a machine of the class described, the combination with a bristle-feeding bristleagitator; and mechanism for agitating the same of a support for a bristle-receiving plate below the agitator; and means for im parting to said support arring vertical movements differing in time from the movements of the agitator.

4. In a machine of the class described, the combination with a bristle-feeding bristleagitator; and mechanism for agitating the same; of a support for a bristle-receiving plate below the agitator; and means for imparting to said support arring vertical movements differing in time and amplitude from the movements of the hopper.

5. In a machine of the class described, the combination with a bristle-feeding bristleagitator; and crank mechanism for agitating the same; of a bristle-receiving plate having a plurality of bristle-recesses; a support for the plate below the agitator; and a cam adapted to impart to said support jarring movements at variance with the movements of the agitator.

In testimony whereof I have hereunto set my hand this 23d day of March, 1905.
